>In 2022 I got both a raise and a bonus.

If your bonus was a significant percentage of your total comp and your tax bracket is ≥24% that scenario will almost always be under withheld and you have to actively engage mid year to compensate if you don't want to true up in April.

>How can I make light over this without paying my CPA a lot to look at each individual paycheck?

Look at your paychecks yourself, ask a question here when you come across as inconsistency that you don't understand.
